Method for content synchronization when broadcasting data in a wireless network

1. A base station configured to synchronize content when broadcasting data in a communications network, the base station comprising: a receiver configured to receive data sequences (PDUs); wherein each received data sequence comprises byte-numbered sequence numbers; the base station further comprising: a transmitter configured to transmit content of the received data sequence; and processing circuitry configured to synchronize transmission with another base station of the content using said byte-numbered sequence numbers, wherein said processing circuitry is configured to determine if a PDU is lost.

2. The base station of claim 1 , wherein the same content is sent from the base station and the another base station in a same radio resource block.

3. The base station of claim 1 , wherein said processing circuitry is configured to determine which PDU or which part of a PDU should be used to resume transmission.

4. The base station of claim 1 , wherein said processing circuitry is configured to use a sequence number of a subsequent received PDU and a sequence number of a last received PDU to determine the lost number of bytes of data and determine a transmission continuation with a subsequent PDU.

5. The base station of claim 1 , wherein the received data sequence comprises a packet-level sequence number and the byte-level sequence number.

6. The base station of claim 1 , further comprising a buffer configured to receive data sequences comprising a packet header and no user data part, said packet header comprising a byte-level sequence number, which is set according to a virtual data associated with said data sequence.

7. A method of a base station for content synchronization when broadcasting data in a communications network, the method comprising: receiving data sequences (PDUs); wherein each received data sequence comprises byte-numbered sequence numbers; transmitting content of the received data sequences in synchronization with another base station using said byte-numbered sequence numbers; and determining if a PDU is lost.

8. The method of claim 7 , further comprising mapping said content to a corresponding radio resource block by relying on the byte-numbered sequence numbers.

9. An arrangement for content synchronization when transmitting data from an infrastructure node in a communications network, said arrangement comprising: processing circuitry configured to add byte-numbered sequence numbers to a data sequence for transmission to a base station; and a transmitter configured to transmit the data sequences with byte-numbered sequence numbers and content to a plurality of base stations, wherein said byte-numbered sequence numbers enable content synchronization by the base station and determining if a PDU is lost.

10. The arrangement of claim 9 , wherein a SYNC protocol enables content synchronization by the base station.

11. The arrangement of claim 9 , wherein the arrangement is configured to obtain the sequence number of a subsequent packet by incrementing a sequence number of a previous packet by a size of the previous packet.

12. The arrangement of claim 9 , wherein said arrangement is configured to add a packet-level sequence number to said data sequences together with a byte-level sequence number.

13. A method of content synchronization when broadcasting data in a communications network, the method comprising: adding byte-numbered sequence numbers to content for transmission in a data sequence to a base station; and transmitting the data sequences with byte-numbered sequence numbers to a plurality of base stations; wherein said byte-numbered sequence numbers enable content synchronization by the base station and determining if a PDU is lost.

14. The method of claim 13 , further comprising mapping said content to a corresponding radio resource block by relying on the byte-numbered sequence numbers.

15. The method of claim 13 , further comprising: determining if a data sequence is lost and which data sequence or which part of said data sequence should be resumed upon transmission; and using a sequence number of a subsequent received data sequence and a sequence number of a last received data sequence to determine the lost number of bytes of data and determine transmission continuation with subsequent data sequence.
